Dead US Satellite Struck By Missile

HONOLULU - A U.S. Navy cruiser blasted a disabled spy satellite with a pinpoint missile strike that achieved the main mission of exploding a tank of toxic fuel 130 miles above the Pacific Ocean, defense officials said.

Destroying the satellite's onboard tank of about 1,000 pounds of hydrazine fuel was the primary goal, and a senior defense official close to the mission said Thursday that it appears the tank was destroyed, and the strike with a specially designed missile was a complete success.

Lets just hope nothing gets though and hits anything or anyone.
 
StarWars practice. Episode II. First one was chinese, now it was american, the next "dead satellite" gonna be from Russia. I bet, they also wanna check their missiles on something.

Kick ass job by the United States Navy!!! :thumbsup:

The heat from reentry should have blown the fuel sky high.

Waste of a good missile.

As for debris falling to earth there would have been less.

what the fuck you lookin at?
Wouldn't it have been more prudent and probably cheaper to go up their and fix the damn thing? Seriously? Satellites cost what...billions?

"Ah fuck it, lets just blow the damn thing up, the tax payers can buy us a new one!"

Pentagon will blast crippled satellite http://board.freeones.com/showthread.php?t=191994

Since this is my field of expertise, and I've worked on some of the components used in this system (and know many others who worked directly on the EKV), please read that information (which is all publicly available and verifiable) before making further assumptions.

Not so fast, they have announced that the threat of debris falling to earth is still there
Okay, this is UTTER BULLSHIT! There is absolutely no "threat of debris," there is just "debris." There is always "debris."

and it will continue to be watched.
Yes, because they want an exact number of particles and their lifespan. The initial debris cloud is far more contained than predicted. The new estimates show nearly all particles entering and burning up in the first 48 hours, and virtually all remaining within 40 days.

Heres another link for those interested.
Apparently you didn't read it. Seriously. Or you "read into it." ;)

Please do not add to what the article actually says.

The heat from reentry should have blown the fuel sky high.
Ahhh, no. Virtually everyone agrees the tank was going to survive. Larger satellites don't fully burn up on re-entry, and a good portion of them will come down.

Waste of a good missile.
Huh?

As for debris falling to earth there would have been less.
Ah, no. High school physics 101, the more surface area, the more heat transfer. It's estimated virtually nothing will not burn up now (we'll know more in a couple of days). It went off even far better than originally predicted.

Ah, no. The US tested it's first and last anti-sat weapon in the mid '80s. The Chinese didn't even tell anyone and blew up a large satellite at a stable orbit, so the junk is going to be around for decades. They also used proximity-fuse, not hit-to-kill, making it far worse and far less obliterated.

This was a satellite re-entry. It was higher than the SM-3 altitude capability. It required a 3rd stage be added for the additional 50% capability. It was also completely unlike a missile defense intercept, we knew the exact trajectory before hand (and had an opportunity at multiple passes).

the next "dead satellite" gonna be from Russia. I bet, they also wanna check their missiles on something.
Actually, this capability is very much wanted by the ESA, NASA and others. The capability to break up a satellite so it doesn't come down and strike the ground is something many have always wanted.

So does a STS launch. Seriously. They only go up and repair when it's worth repairing. This one was not. Some things can't be fixed in orbit and/or re-inserted. And STS is not the "most reliable/available" repair platform right now. NASA is not using it for anything other than completing the ISS and other duties it can't avoid -- let alone they needed to do that back in 2006 (when STS wasn't exactly being used much ;) ).

It is cheaper and much safer to just launch another spy satellite.

About the only thing I've seen repeatedly, and most of my former engineering colleagues have seen, is rhetoric. Technically, this is a 100% peaceful use of a technology never designed for it. It's actually kinda cool to have this capability now, which can be used by space agencies, or even other militaries that want something destroyed so it does not come down on others.

About the only thing you don't want to blow up is something with an RTG in it. Those will survive and stay intact after a crash, at least US, European and Japanese designs. The Russians have been guilty of some poor encasings on theirs though.
 
They should build a self-destruct in to the Satellites, so we don't have to think about them coming down.

We can just push a button and blow them up.

Or missiles have them why not are Satellites.

AH! That makes sense! We're Americans we don't do things like that! That's just a silly question.

That would just add weight and there would always be a chance that something would go wrong and it would destroy a piece of equipment costing millions of dollars to make and be hard to get back up there. Plus sooner or later some other entity would hack into the signal to activate and destroy it prematurely.
